Design Patterns in Practice: Strategy for Configurable Rules
How to apply Strategy to keep business rules configurable without compromising code clarity.
Includes a small decision table, default fallbacks, and runtime selection.
When to Use
- Multiple algorithms for the same workflow.
- Frequent rule changes from business needs.
- Need to test rules independently.
设计模式实践：用策略模式管理可配置规则
用策略模式隔离规则变化，让业务逻辑可配置且代码清晰。
包含决策表、默认兜底与运行时选择建议。
适用场景
- 同一流程多种算法。
- 规则频繁变化。
- 需要独立测试规则。
